A2, A3, and B2 Filter Coefficient
Format (52h, 54h, 56h)
Filter coefficients A2, A3, and B2 are stored as 16-bit
two’s complement values in the -4 to (4 - 2-13) range.
The transfer function equation is as follows:
A2 = int (N x 213)
where N is the decimal coefficient value.
The following are two examples of the transfer function
equation:
Example 1:
N = 2.381
A2 = int (2.381 x 213)
A2 = int (19505.152)
A2 = 19505 = 4C31h (two’s complement)
Example 2:
N = -2.381
A2 = int (-2.381 x 213)
A2 = int (-19505.152)
A2 = -19505 = B3CFh (two’s complement)

Power Supplies, Layout, and
Bypassing Considerations
For best performance, use PCBs with ground planes.
Ensure that digital and analog signal lines are separat-
ed from each other. Do not run analog and digital lines
parallel to one another (especially clock lines), and do
not run digital lines underneath the MAX11043 pack-
age. Use a single-point analog ground (star ground
point) at AGND, separate from the logic ground.
Connect all other analog grounds and DGND to this
star ground point. Do not connect other digital system
grounds to this single-point analog ground. The ground
return to the power supply for this ground should be
low impedance and as short as possible for noise-free
operation. Bypass all supplies to ground with high
quality capacitors as close as possible to the device.
